Space charge distribution detection by FLIMM and PEA method on electron beam irradiated dielectric films

Decay of space charge in conjugated polymers measured using pyroelectric current transients J. Appl. Phys. 93, 2884 (2003) The space charge accumulation phenomenon has garnered great interest over the last two decades because of the increased use of direct current in high voltage electrical systems. In this context, a significant relevance has been achieved by the thermal methods, used for solid dielectrics. This paper presents a review of this non-destructive measurement system used for the measurement of space charge. The thermal pulse method, the thermal step method, and the laser intensity modulation method are described. For each configuration, the principle of operation, the thicknesses analyzed, and the spatial resolution are described, reporting also the main related applications. Published by AIP Publishing.

In this work, we focus our attention on data obtained from Pulse Electro Acoustic (PEA) measurements on PTFE films before and after irradiation with a 60 Co gamma radiation source. At first, samples are just polarized to determine the effect of the gamma irradiation on the charge transport in the bulk. In a second stage, these films have been exposed to a mono-energetic electron beam. The aim is to study the effect of gamma radiation on charge storage in the bulk.
